Working on a project and after a while when I press Ctrl+S (or Save) the asterisk before the project's name (in the window title) doesn't disappear.
When you close the Ardour you'll have all three options "Don't quit", "Just quit", and "Save and quit", instead of two options "Don't Quit" and "Just Quit".

The changes are actually saved since if I close and choose "Just Quit", the changes are there.

Steps To Reproduce

I couldn't understand how to reproduce exactly, I almost in every projects after a moment this behavior starts to appear and remains for the rest of the changes I am doing in that project.

Observation:

Opened the project where one track was soloed. Modified the fader envelope in the track (asterisk appeared). then pressed Ctrl+S (asterisk disappeared). Unsoloed all tracks (asterisk appeared). After that every changes I am doing and press Ctrl+S, doesn't make asterisk to disappear.
